Gravitas Plus: Do you sleep for less than 7.5 hours? Watch this

hello and welcome to gravitas plus i'm palki sharma how many hours of sleep did you get last night five three or maybe you did not sleep at all last night after all it's a weekend and it's only normal to spend weekend nights watching something or reading or just staying up chatting with friends basically doing anything but sleeping why waste time sleeping when you can do so much right correct me if i'm wrong but sleep is often seen as time wasted lost forever there are proverbs that warn you about being left behind while sleeping in practically every language there are idioms like caught napping or burning the midnight oil so those who want to make something of themselves in life cut down on sleep an average adult sleeps for 6.8 hours a night the national average in japan is 5 hours and 59 minutes saudi arabia 6 hours 8 minutes sweden 6 hours 10 minutes india 6 hours and 20 minutes do you know these numbers can kill us science says an average adult needs to sleep at least seven and a half hours every night in these seven and a half hours a person completes five 90-minute sleep cycles during these cycles your brain moves from deep non-rapid eye movement sleep to rapid eye movement sleep the first couple of cycles are dominated by non-rem sleep it cleanses and maintains our body brain and heart the next set of cycles are needed for processing and learning all the information that we've gathered throughout the day if you're having trouble recalling names information or trivia blame it on your sleep or lack of it seven and a half hours per night is the recommended amount of sleep america's center for disease control is a little more practical it says seven hours or more this applies to all adults borrowing just three to five percent of the population they can do with less than six hours of sleep courtesy a rare gene mutation read this article for more as for the recommended amount of sleep for other age groups here is a chart now that we know how much we should sleep the next question is when should we sleep can we complete our sleep quota in the mornings afternoons and evenings too again here's what science says people are at their sleepiest at two points in the day between 1 pm and 3 p.m and between 2 a.m and 4 a.m the best time to go to sleep is between 8 pm and midnight early to bed early to rise give a man his dose of vitamin d the vedas say we should wake up around 3 30 a.m it's called the brahma muhurit the time of the creator but this is impossible in the world that we have created for ourselves most of us work shifts or late into the night what happens if you sleep after midnight this study says late bedtime is related to depressive symptoms some experts believe that if you sleep by 2 am but complete your 7 and a half hours of sleep you're safe meaning there is no risk of cardiovascular disease or diabetes as such but there's a catch here if you're sleeping late you need to ensure that your sleep is undisturbed that really doesn't happen does it with the morning come doorbells work calls the noise of traffic school college milkman everything as a result our sleep is hampered and we end up sleep deprived next question what happens if you're not sleeping enough there is a drop in health and productivity let's look at health first sleep deprivation is linked to physical health problems like cardiovascular disease hypertension diabetes studies have found that lack of sleep is also linked to breast cancer in women and prostate cancer in men and i'm not making this up researchers at hong kong university conducted a study they found a discernible dna damage in those whose sleep was disrupted even for one night experts say this may help explain the link between cancer and sleep deprivation let's look at mental health problems now lack of sleep is linked to anxiety and depression south korea and japan rank the worst when it comes to a good night's sleep it so happens that south korea and japan also have the highest suicide rates in the world japan has the phenomenon called karoshi death caused by lack of sleep do you know we also put on weight if we don't sleep well king's college london conducted a study in 2016 it found that sleep deprived people consumed an average of 385 kilo calories extra per day that's an excess of four and a half slices of bread every day a study was carried out by researchers at the pennsylvania state university this is as recent as 2019 researchers studied people in their twenties half of the volunteers got regular sleep the other half slept less than five hours each night now the sleep deprived lot ended up feeling less full than the others after eating a high-fat meal leptin and ghrelin are two hormones that explain the link between sleep deprivation and obesity leptin tells the brain that you're full ghrelin urges you to eat more sleep deprived people have low levels of leptin and high levels of ghrelin sleep deprivation is also linked to the lack of productivity if you don't get enough sleep you're groggy at work it's also hard to concentrate you know the drill we've all been there as a result people end up being less productive the united states loses the equivalent of around 1.2 million working days per year because people are not getting enough sleep in japan around 600 000 working days are lost in the uk and germany the number becomes 200 000 this loss affects your country's gdp these numbers are according to the rand corporation and this is something that india should be looking at closely you know why because in india staying back late at work and sleeping less is regarded as professionalism so here's the moral of the story so far sleep deprivation is helping no one except the market brands are capitalizing on a lack of sleep on our habits till around 1880 people were sleeping an average of 10 hours a night thomas edison then invented the light bulb 141 years later we also have phones laptops and tablets

promising sleep they come bottled in the form of lotions candles sleep comes in paid apps that play sleep inducing sounds do you know falling asleep takes around 10 to 15 minutes but if you manage to doze off within a few minutes it means that your sleep deprived sleep today has become a product in fact a luxury product the sleep tech device market is worth over 10.9 billion dollars 48.5 of this
